Constructor Grafari Reviews & Product Details

Constructor Grafari Orthograph is adaptive spelling software for students from grade 2 onward, including children with dyslexia and students learning the language as a second or foreign language. Students build spelling skills on their own and at their own pace in short sessions, while teachers follow each learner's progress. Orthograph is built on a multisensory method. Instead of plain black-and-white text, each word is shown as a structured sequence of colors, shapes, sounds, and patterns. In the early stages this helps learners link sounds to letters automatically, and later it helps them recognize spelling patterns. The vocabulary covers about 8,000 high-frequency words, organized by spelling pattern. The program adapts to every learner, repeating words more or less often depending on how they perform, with no setup by the teacher. Learners get immediate feedback and are encouraged to correct their own mistakes. Units last 15 to 20 minutes and can be done at school or at home, and a reward park keeps children motivated. Teachers use coaching and monitoring tools to support individual students or whole classes and to track progress. Orthograph was developed by researchers at ETH Zurich and studied at ETH Zurich and the University of Zurich. In a study of children with dyslexia who trained for 15 to 20 minutes, four days a week, for three months, writing improved by 19% to 35%, compared with 0% to 9% for children who did not train (Kast et al., Restorative Neurology and Neuroscience, 2007). A later study found that children with dyslexia improved their spelling as much as children without dyslexia (Kast et al., Annals of Dyslexia, 2011). It runs in the browser on computers and tablets.
